Seitoubatsutai Rei & Saki C-R-O-S-S

Vampires are nearly impossible to destroy, as they can rise again even from ashes. However, there are ways to significantly delay their return. This requires two people: one to physically overpower the vampire, and another to use faith-based abilities. Saki is close to completing his training as an Invocator, needing only to pass a final test. His partner is unusual, and it seems unlikely that such a small and seemingly weak individual could match vampires in terms of power and agility.
